11 | - should handle some moose-specific options in &Moose::Meta::Class::create |
12 | things like roles, and method modifiers (although those can probably be |
13 | ignored if i want to) |
14 | |
8b59f8d6 |
15 | - type unions |
16 | |
17 | Add support for doing it with Classes which do not have |
18 | a type constraint yet created |
19 | |
20 | - type intersections |
21 | |
22 | Mostly just for Roles |
23 | |
24 | - inherited slot specs |
25 | |
db1ab48d |
26 | 'does' can be added to,.. but not changed |
27 | (need type unions for this) |

29 | - proxy attributes |
30 | |
db1ab48d |
31 | a proxied attribute is an attribute |
32 | which looks like an attribute, |
33 | talks like an attribute, smells |
34 | like an attribute,.. but if you |
35 | look behind the curtain,.. its |
36 | over there.. in that other object |
37 | |
38 | (... probably be a custom metaclass) |

40 | - compile time extends |
41 | |
42 | [00:39] sri but maybe a better syntax for compile time extends |
43 | [00:39] stevan I have been pondering that actually |
44 | [00:39] sri use Moose extends => Foo::Bar |
45 | [00:40] stevan I think now that we have the Sub::Exporter stuff |
46 | in, that kinda thing should be pretty easy |
47 | |
8245db56 |
48 | nothingmuch notes that all the constructs should be supported in the entirety of the use clause: |
49 | |
50 | use Moose ( |
51 | has => foo ( |
52 | .... |
53 | ), |
54 | ); |
55 | |
56 | and that if this usage style is used nothing is exported to the namespace. |
57 | |

58 | - default should dclone() |

60 | - subtype $anon_subtype => where { ... } |
61 | |
62 | [22:56] stevan sub mst_doesnt_like_to_type { (shift)->meta->attr->type_contstraint } |
63 | [22:57] mst err |
64 | [22:57] stevan :P |
65 | [22:57] stevan are you wanting to reuse it or something? |
66 | [22:57] stevan my $subtype = subtype 'Something' => where { ... }; |
67 | [22:58] stevan then you can do isa => $subtype |
68 | [22:58] mst but I can't subtype it again |
69 | [22:59] stevan mst: ahhh... |
70 | [22:59] mst well, I can. but it suddenly gets very "long way round" ish |
71 | [23:00] stevan my $constraint = Moose::Meta::TypeConstraint->new( |
72 | [23:00] stevan name => $name || '__ANON__', |
73 | [23:00] stevan parent => $parent, |
74 | [23:00] stevan constraint => $check, |
75 | [23:00] stevan message => $message, |
76 | [23:00] stevan ); |
77 | [23:00] stevan yeah thats kinda the long way |
78 | [23:00] stevan mst: what would you like it to be? |
79 | [23:00] mst $parent = find_type_constraint($parent) if defined $parent; |
80 | [23:00] mst if $parent is already a type constraint |
81 | [23:00] mst skip that bit |
82 | [23:00] stevan hmm |
83 | [23:00] mst should be all you need to change |
84 | [23:00] stevan yeah |
85 | [23:01] stevan so you can then say |
86 | [23:01] stevan subtype $anon => where { ... }; |
87 | [23:01] mst right |
88 | [23:01] stevan ok |
89 | |
90 | - method keyword |
91 | |
92 | [23:37] mst more seriously, I'd still like a "method" keyword or something |
93 | [23:37] mst method 'foo' => sub { ... }; |
94 | [23:38] stevan what would it do more than sub foo { ... }? |
95 | [23:39] stevan I would like multimethods actually |
96 | [23:39] mst almost exactly nothing, to begin with |
97 | [23:39] stevan but thats just cause I love CLOS and am reading a book on Dylan now |
98 | [23:40] stevan keyword squating :) |
99 | [23:40] mst but if we need to hook stuff later it's bloody handy to already have people writing it that way |
100 | [23:40] mst right |
101 | ... |
102 | [23:49] mst oh, also: method 'has' => sub { ... } could squelch the redefine warning |

104 | - local coerce |
105 | |
106 | [13:16] mst stevan: slight problem with coerce |
107 | [13:16] mst I only get to declare it once |
108 | [13:17] mst so if I'm trying to declare it cast-style per-source-class rather than per-target-class |
109 | [13:17] mst I am extremely screwed |
110 | [13:17] stevan yes |
111 | [13:17] stevan they are not class specific |
112 | [13:18] stevan they are attached to the type constraint itself |
113 | [13:18] * stevan ponders anon-coercion-metaobjects |
114 | [13:18] mst yes, that's fine |
115 | [13:19] mst but when I declare a class |
116 | [13:19] mst I want to be able to say "this class coerces to X type via <this>" |
117 | [13:19] stevan yeah something like that |
118 | [13:19] stevan oh,.. hmm |
119 | [13:20] stevan sort of like inflate/deflate? |
120 | [13:20] stevan around the accessors? |
121 | [13:25] * bluefeet has quit (Remote host closed the connection) |
122 | [13:27] mst no |
123 | [13:27] mst nothing like that |
124 | [13:27] mst like a cast |
125 | [13:31] mst stevan: $obj->foo($bar); where 'foo' expects a 'Foo' object |
126 | [13:31] mst stevan: is effectively <Foo>$bar, right? |
127 | [13:32] mst stevan: I want to be able to say in package Bar |
128 | [13:32] mst stevan: coerce_to 'Foo' via { ... }; |
129 | [13:32] mst etc. |
130 | [13:53] stevan hmm |

137 | - Moose "strict" mode |
138 | |
139 | use Moose 'strict'; This would allow us to have all sort of expensive tests |
140 | which can be turned off in prod. |
141 | |
142 | - Moose::Philosophy.pod |
143 | |
144 | To explain Moose from a very high level |
145 | |

146 | - moosedoc |

147 | |

148 | We certainly have enough meta-information to make pretty complete POD docs. |
